From the linked article…
In a day and age when literally everyone connected to a film production gets a credit, from craft services to on-set teachers of child actors to random “production babies” who didn’t even work on a film, it is utterly incomprehensible that vfx artists, whose work makes possible the final images that appear onscreen, are routinely omitted from screen credits.
I can attest to this, having worked in the field. Most of the work in TV and cinema goes uncredited, with team leaders or just the post houses at most being recognized with an end credit placement (by contract, of course). I understand totally that it is always a team effort and hardly any of the viewing public sits through the entire end credits roll. I totally get it. But when it happens that you are included, that small token of recognition does remind you why you’re doing 12-hour days erasing power lines, making day look like night, adding/removing people and/or signage from shots they weren’t supposed to be in and pushing greenscreened people in front of moving cars.
I mean, there are also production offices, editors, post-production supervisors, and Universal’s contract with DNEG involved.
If he missed it, then so did dozens of other people. Though the fact that DNEG just laid off like 8% off their workforce in London makes me think that it was a deliberate decision from the studios rather than “Nolan forgetting to do it”
